The invention relates to an apparatus (10) for securing sealing elements (12, 14) in a recess (16), more particularly in an installation slot in a turbomachine, having at least one sealing support element (18) comprising at least one sealing element (12, 14). At least one fixing piece (20) is fitted between the sealing support element (18) and a clamping piece (22) associated with the sealing support element (18), and the fixing piece (20) is integrally joined to the sealing support element (18) and the clamping piece (22) by strut-like connections (24) that can be broken by the application of force. The invention also relates to a securing method and to a method for manufacturing the claimed apparatus (10).

1. An apparatus for securing sealing elements (12, 14) in an installation slot formed in a turbomachine, having at least one sealing support element (18) comprising at least one sealing element (12, 14) wherein at least one fixing piece (20) is disposed between the sealing support element (18) and a
1. An apparatus for securing sealing elements (12, 14) in an installation slot formed in a turbomachine, having at least one sealing support element (18) comprising at least one sealing element (12, 14) wherein at least one fixing piece (20) is disposed between the sealing support element (18) and a clamping piece (22) associated with the sealing support element (18), wherein the fixing piece (20) can be joined integrally to the sealing support element (18) and to the clamping piece (22) by strut-like connections (24) that can be broken off by means of applying force. 2. The apparatus according to claim 1, wherein the fixing piece (20) is formed in such a way that when the connection is broken between the fixing piece (20) and the sealing support element (18), and between the clamping piece (22) and the fixing piece (20), a force closure is achieved between the fixing piece (20), the sealing support element (18), the clamping piece (22) and side walls of the recess (16). 3. The apparatus according to claim 1 wherein the sealing support element (18) is formed as a housing for the uptake of the sealing element (12). 4. The apparatus according to claim 3, wherein the sealing element (12) is formed as a brush seal. 5. The apparatus according to claim 1, wherein the sealing support element (18) is designed as the base element of the sealing element (14), wherein the sealing element (14) is a labyrinth seal. 6. The apparatus according to claim 5, wherein the fixing piece (20), the sealing support element (18), the clamping piece (22), the strut-like connections (24) and the sealing element (14), which is a labyrinth seal, are formed in one piece. 7. The apparatus according to claim 1, wherein the strut-like connections (24), each projecting from the sealing support element (18) and the corresponding opposite-lying clamping piece (22) are configured with the formation of an angle pointing in the direction of the recess (16). 8. The apparatus according to claim 1, wherein a space formed between the sealing support element (18) and the opposite-lying clamping piece (22) is tapers in the direction of the recess (16) for the uptake of the fixing piece (20). 9. The apparatus according to claim 1, wherein a free space (26) resides between an end (38) of the fixing piece (20) pointing in the direction of the recess (16) and a base (28) of the recess (16). 10. The apparatus according to claim 1, wherein the fixing piece (20) tapers in the direction of the recess (16). 11. The apparatus according to claim 10, wherein the fixing piece (20) is has a shape of a wedge or truncated cone. 12. The apparatus according to claim 1, wherein the fixing piece (20), the sealing support element (18), the clamping piece (22), and the strut-like connections (24) are formed in one piece. 13. The apparatus according to claim 1, wherein: a) the apparatus (10) resides in a recess (16);b) an introduction of a force in the direction of the recess (16) onto the fixing piece (20) causes the connection between the fixing piece (20) and the sealing support element (18), and between the clamping piece (22) and the fixing piece (20), to be broken; andc) further introduction of force onto the fixing piece (20) until a force closure results between the fixing piece (20), the sealing support element (18), the clamping piece (22), and side walls of the recess (16). 14. The apparatus according to claim 1, wherein the apparatus (10) is produced by an additive manufacturing method. 15. The apparatus according to claim 14, wherein the additive manufacturing method is a selective laser melting method or a selective laser sintering method.
